IMPROVEMENT IN SILK-SPINNING FRAMES.

To all whom it may eoncem:

Be it known that I, JOHN E. ATWOOD, of

Mansfield, in the county of Tolland and State` of Connecticut, have invented certain Improvements in Spinning-Frames, of which the following is a specification: y l

This invention mainly relates to frames for "mp-spinning 5 andis more especially designed er, lighter, steadier, and more compact than when duplicate reels onV opposite sides of the frame are used.` This arrangement of the spindle-drivers and. their belts admits of a most eii'ective driving-belt surface and proper line of draft for .the belts within a narrow frame. The invention also consists in a novel and advantageous stop mechanism for automatically stopping the spinning-frame when a given quantity of yarn or warp has been taken up on the reel, said mechanism comprising an adjustable cam-plate on a ratchetwheel receiving its motion from the reel, and an adjustable sleeve with attached linger, operated by the cam-plate for actuating the shipping-lever.

In the accompanying drawing, Figure 1 represents an end elevation of a spinning-frame for up-spinning, having my invention applied; Fig. 2, a vertical transverse section of the same through the reel; Fig. 3, a horizontal section7 in part, on the irregular line :v x,- and Fig. 4, a longitudinal section, in part, mainly on the line y y.

A A are the end or supporting standards of Vthe frame, and B B the spindle rails or girts, carrying spindles C C on opposite sides of the frame. D is the single reel, arranged overhead between the two sets of spindles, and rotated by gearing in any suitable manner, E being the reel-shaft. Said reel it is preferred to build up in sections of any desired length, united by couplings which will provide for the independent removal of the sections by simply lifting them from their places, but when in opera-tion they virtually form a single reel and rotate in common, and in the same direction. The yarn bvb runs off onto the upper side of the reel from the spindles C on the one side of the frame, and onto the lower side of the reel from the spindles C on the other side of the frame, as shown. Thus using a single reel is a great advantage in many respects, but principally in the reduction which it makes Vin space, and in the size and weight of the frame. This will readily be seen when it is understood that ordinarily forty-inch reels have been used in pairs, one reel on either side, which consequently requires a very wide frame.

By using a single reel I obtain a narrow frame, and in order to properly drive the spindles in a frame reduced in width as much as possible, I employ duplicate intermediate horizontal spindle-drivers B1 B2, with belts or bands b', (one only of which latter is here shown, but the arrangement is similar for each,) and each spindle-driver Bl or B2 serves to operate the spindle or spindles on the side ofthe frame farthest from it, each belt b passing under the other spindle-driver. This gives a most effective belt-surface, and the draft of the belt is at right angles to the spindle.

The stop mechanism is constructed as follows: F is a pinion on the reel-shaft, giving motion to a wheel, G, which, in its turn, actuates a pinion, H. On or connected with this pinion H is an eccentric, I, which gives motion to a toothed rod or dog, J, for the purpose of operating a ratchet-wheel, K, one or more teeth at a time for each revolution of the pinion H. The ratchet K has a screw-threaded eye or socket, which forms its bearing on a screw-stud, L, so that as the ratchet is moved by the dog J it travels along the screw-stud, and in due course, or after a certain amount of motion, causes a tooth or projection, d, on a plate, M, which may be termed a cam-plate, carried by the ratchet, to act on a finger, e, of a sleeve, N, fast to a free stud or sleeve, O, and so to rock the latter. This causes another linger or catch, f, on the sleeve O to be released from its hold of a belt-shipper, P, which latter then flies back by the agency of a spring, g, and throws the driving-belt from the fast pulley Q, onto the loose pulley R, and so stops the machine. The fingers e fare held in position prior to action by the cam-plate M, by a spring, h. The nger e or sleeve N carrying it is adjustably secured, by set-screw or at different points in a Whole revolution ofthe ratchet K, the cam-plate M is made adjustable on the face of the ratchet by means of a screw and curved slot, l, Which accordingly throws the tooth d farther forward or back.

I claim- 1. The combination, with the spindles C, on both or opposite sides ofthe frame, and a single take-up reel, D, arranged to receive the yarn onto its upper and lower sides from the spindles on the opposite sides of the frame, of the duplicate intermediate horizontal spindledrivers Bl B2, and their belts or bands b', arranged as shown, so that each spindle is driven from the driver on the opposite side of the frame, substantially as specied.

2. The combination, in a stop mechanism, of the toothed rod or dog J deriving its motion from the reel, the ratchet-Wheel K, having a screw-bearing, L, the adjustable cam- Wheel M, the adjustable linger e or sleeve N carrying it, the rocking stud or sleeve 0, and the linger or catch f for release of the beltshipper, essentially as described.
